Definitions

  • the invention relates to an intake system for an internal combustion engine, in particular for a motor vehicle engine according to the preamble of the main claim.
  • an intake system for a multi-cylinder internal combustion engine is known, which is designed as an intake system.
  • a large number of intake pipes are normally required, which feed the cleaned intake air from a collecting duct to the individual intake openings in the cylinder head of the engine.
  • the intake system is usually made of aluminum or plastic and is manufactured using a casting or injection molding process.
  • a disadvantage of such systems is the complex manufacturing process. For example, it is known to produce an intake system using the core melt process. A metal core, which later forms the system's cavity, is overmolded with plastic and this metal core is then melted out. It is also possible to produce such an intake system, in particular in plastic using multi-shell technology, that is to say to form individual plastic shells and to weld them together.
  • the invention has for its object to avoid the disadvantages mentioned and to create an intake system that is easy to manufacture and without high assembly costs. This object is solved by the features of the main claim.
  • the main idea of the invention is to manufacture the very irregularly shaped intake pipes, which make the manufacturing process considerably more difficult, from one or more blow-molded parts and to connect these blow-molded parts with flange elements or other plastic components, which have a simple structure.
  • the blow part When the blow part is connected to a connecting flange and other elements, it makes sense to design the connection point to be vibration-decoupled.
  • this egg-elastomeric mass represents a reliable connection between the two elements.
  • Another advantage of using blow molded parts is that the length of the vibrating tube can be varied, which means that optimization is possible without great effort.
  • a preferred further development of the invention provides that the elements that are not produced in plastic blowing technology are produced from thermoplastic material by injection molding.
  • the further connection offers the possibility of providing the intake system with an additional line duct which can be switched on or off according to the speed of the engine and the load condition.
  • glass-fiber reinforced thermoplastic the glass fibers being so-called long fibers.
  • These long fibers have the advantage that they accumulate anisotropically in the plastic and the behavior of the plastic with respect to warpage is isotropic.
  • Polypropylene or polyamide can preferably be used as the plastic. Due to the simple manufacture of the collection unit, additional elements such as throttle valve, air flow meter and other necessary components can be integrated therein.
  • FIG. 1 shows an intake system in a schematic representation in cross section
  • FIG. 2 shows in detail a connection between the plastic blow part and a connecting flange
  • FIG. 1 shows an intake system consisting of an intake pipe 10, a flange 11, a collecting unit 12 with a cover 13.
  • a switching drum 14 which connects an opening 15 with the collecting unit 12 in the position shown here.
  • the intake pipe is connected at the connection point 16 to the flange 11 and the connection point 17 to the collecting unit 12. While the entire intake system is attached to the cylinder head of an internal combustion engine, not shown here, via the flange 11, this system is supported on the opposite side by the support or fastening elements, not shown here.
  • connection point 16 or connection point 17 is shown in a detailed illustration in FIG. 2.
  • the elastomer is suitable for effectively dampening vibrations that are introduced into the intake system, for example, via the flange element 18.
  • the opening 15, between the collecting unit 12 and the intake pipe 10, can also be formed from an elastomeric material. This also prevents vibrations from being transmitted from one component to the other.
  • FIG. 3 shows a top view of an intake system.
  • the individual intake pipes 10 a to 10 f are combined in groups of three.
  • a group of three is blown from a single tube. This hose is squeezed between the suction pipes to be formed, so that two pinch seams 19, 20 and 19 a, 20 a are set.
  • the two tube groups can be connected to both the flange 11 and the collecting unit 12 in one operation.
  • a throttle valve schematically shown here, for regulating the air volume is integrated in the collecting unit.
  • other elements such as valves, oil separators or the like can be connected in or on the collection unit.
